I'm finding with Fire Force, as with a lot of manga series, that a lot of the books up until this moment have been filled with filler content. I know a lot of this is to make you love the characters and develop a kinship with them, but I feel like in a world that is becoming as complex as the Fire Force universe, some of these volumes could have been used to lend more to the storyline. It's good, I just find a lot is happening at once.
